Hi all,
I've pretty much sorted all of my main issues configuring Multicast Helper-Maps but there is one thing I'm having issues with.
I'm using the following config:
ACL:
ip access-list extended CISCO3000
permit udp any host 10.1.1.255 eq 3000
ip access-list extended CISCO4000
permit udp any host 10.1.1.255 eq 4000
ip access-list extended CISCO5000
permit udp any host 10.1.1.255 eq 5000
Interface Gi0/1
ip multicast helper-map broadcast 239.3.3.3 CISCO3000
ip multicast helper-map broadcast 239.4.4.4 CISCO4000
ip multicast helper-map broadcast 239.5.5.5 CISCO5000
I'm using Ostinato packet generator, sending broadcast packets to 10.1.1.255:3000 and I can see the ACL match increment against CISCO3000 which is great. But when I send packets to that broadcast address via port 4000 and 5000 I'm getting no matches against the ACLs CISCO4000 & CISCO5000.
Ideas?

Hello
Have you specified the specific UDP and port to be forwarded?
What igp are you using?
Can you post the config of you first/last hop rtr?
